R33 Rb 25 Det Turbo Upgrade ?

[jet2nv]

So the gt3071 should hit 280rwkw on 98 fuel mate if ur keen I might be selling a Garrett 3071r only done 500kms

[Harey]

In summary:

HKS 2530 for 230rwkw and great response

Hypergear Hiflow for 250-270rwkw and factory appearance

HKS2835 Pro S for ultimate response vs top end power turbo but very costly

GT3076 for 300rwkw, prob just wait for GTX3076 though.

[jet2nv]

What about the gt3071r power wise?

[R31Nismoid]

upto 270-280rwkw with better response than a 3076 obviously

[75coupe]

well all that being said, go the HKS 2835 GT ProS... with full front facing plenum, FMIC, 3.5: all through exhaust no cat, 800cc + injectors on e85 tune... then just pay for tyres...

[geraus]

Hypergear Hiflow for 250-270rwkw and factory appearance,

my cars pulling about 250kws, and let me tell ya the power delivery is awesome!

Not sure why people are still talking about 3071s, there is that much info on this forum about what those turbos are and what those turbos can do that you could not piss in the wind and NOT hit one of those threads.

The OP has asked for 240kw, has stated he is on a budget.

Unbolt your turbo, send it to hypergear, pay about $1000, tell him you want an easy 240kw, get it back bolt it back on AS IT CAME OFF, do the supporting mods and enjoy your 240rwkw.

End of story. Hypergear has been successful in getting 300rwkw out of highflow turbos, 240rwkw is well within his ability to create a worthy high flow turbo.

You are going to need the following at a minimum:

Injectors - see status on this forum for highflowing injectors

Z32 - get a used one with a plug classifieds on this forum

Remap ecu - see toshi on this forum

Fuel pump - see boostinimports on this forum

Boost tap - get a turbotech for $30 on ebay (THE BEST)

End.

Agree with the above post.

Except maybe for the ECU look at the Nistune ECU, and also someone correct me if im wrong last time I checked Trent no longer highflows injectors.

Though maybe if you asked nicely he would

[Toshi]

240kw do not need bigger injector.

You need Z32 AFM,hiflow fuel pump and bigger turbo.

[JonnoHR31]

every cars different. i maxxed standard injectors at 185rwkw, other people get 250rwkw out of them. theres a lot of variables

[W0rp3D]

210 see's 100% duty cycle on mine, but i havnt upped the rail pressure either.

185 kw is too low.

I think fuel pump or injector (need clean) problem.

Also your fuel pump is not hiflow (like a Bosch 040) or airflow meteor problem.

Please calculate how much power is able to make from 370cc injector.

I made many 220-260kw hiflow turbo with std injector R33 GTS-T.

highflow looks stock, makes the power required and is the cheapest

go for gold

have an external bosch 044 hardwired, certainly no issues there.

main reasons were, conservative tune and hitting slightly richer cells on cold mornings. like i said theres a lot of variables and some cars cant make that much power with standard injectors, simple as that

you sure you aren't talking about an rb20? they max around 200 or lower but rb25 injectors will do 220kw+ every single day

[JonnoHR31]

definately rb25 and definately factory 370cc injectors

like i said, every car and dyno is different, some cars will happily do 220+ but some wont

Its not different if fuel system is healthy.

[JonnoHR31]

so dynos, timing, exhaust restrictions, turbo setups etc all play no part whatsoever?

[wolverine]

Dynos are all the same, everyone knows that.

They all give a different number.

Don't stock injectors runs out of puff around 230rwkws?
